IMPROVEMENT IN Benson-LOADING sins-Anus.

TO ALL WHOM IT MAY CONCERN:

-Be it known that-I, ISAAC'iM. MILBANK, of Greenfield Hill, -in thecounty of Fairfield,'an'd State of Connecticut, hare invented, made, andapplied to use, a certain new and useful Improvement inBreech-Loadingllire- Arms; andI do hereby declare the following to be afull, clear, and exact description ofthe said invention, reference-beinghad to the annexed'drawing, making partof this specification, 'whereinFigure 1 is a side ,view, showing the improvement; and v Figure 2 is aplan of the same, the breech being shown open dotted red lines,

. Similar marks of reference denote the same parts. p

Breech-loading fire-arms have her'etofore bcen made with a'breechswinging out horizontally, erud te-the right of the piece. Fire-armshave also beenmade with a breech that swings on an axis parallel to thehammer axis, and is blocked into place by the action of the hammeritself as it strikes' against the breech. The nature of my saidinvention consists in a wing applied to the horizontal swinging breechblock, over which; wing the hammer-shank closes before the hammer-headstrikes the detonating cap or punch, thereby holding the breech securelyclosed against the explosion of the cartridge; and in case, the breechis not properly closed, the explosion cannot take place in consequenceof the hammer being arrested by coming in contact with the end of saidwing.

In the drawing,-a represents a portion of the stock, and b a; portion ofthe barrel [of a fire-arm, of any desired size or construction. In theside of the barrel bis an opening or mortise, in which is placed thebreechblock 0, attached at its forward end bythe hinge d to the barrelb,and I pref r. and use a metalstrap, e, surrounding said barrel, andforming the top and bottom portions of said hinge. The opening in thebreechblock 0, for the hinge-pin i, is to be ;sl ightly elongated, inorder that the rear end of the breech block may be allowed to set firmlyagainst the back end of the mortise into which the breech-block isclosed; thereby the hinge itself will be relieved of any undue strainwhen the piece is fired. h is a wing extending to the rearof ,thebreech-block c, and formedwith or attached to'thc same, and this wing 7tis of such a size and shape as to pass into a recess into the stock justin front of the hammer 70 when. cooked, as seen in the drawing.. Whenthe hammer is discharged, its shank passes down at the side of the wing71, retaining the same firmlyfso that the explosion cannot throw out therear end of the breech-block c. The hammer k, in discharging the piece,strikes on the rear end of thopunch m, if alm'etallic cartridge isemployed; or a nipple and cap may be used in place of the 'punch m. Ifthe breech c is not entirely closed, the hammer is arrested by takingagainst the end of the wing J, and does not reach the punch or nipple;hence no injury cun'r-esult from the explosion, as that is prevented- 4;In order to strengthen thehammer in resisting any sidewise pressurefrom the wing h, I make'use of looking projections, 72 and o, the one,at, being a catchrextendin'g outdaterally from the rea r end of thebarrel, with an end or head to the right and outer side of the recessinto which the projection 0 on the under side-of the hammer falls as thehammer is discharged; and thereby a support is formed for the-upper endof'the hammer when discharged, and during the time that the p'arts areunder the strain-of theexplosionl What I claim, and desire to secure byLetters Patent, is-- 1. The wing it, in combination with the swingingbreech-blook'c, and hammer k, for the purposes and substantiallyas setforth. 4

"2. I claim the locking projections n and 0, in combination with thehammer k-and wing h of the swinging breech block, asand for the purposessetforth.
